The innovative Intelligent Spectral Analyser (ISA) is a compact UV/VIS spectrometer that allows the simultaneous acquisition of a multitude of parameters with only one sensor. In addition to classic water quality parameters, this optical sensor allows the simultaneous analysis of a multitude of other ingredients and water properties by means of chemometric methods. The system version is composed of the sensor head, which is directly connected to the BlueBox Controller via an optical fiber.
Available parameters
The ISA UV/Vis spectrometer is always calibrated on site using laboratory values. This customer-specific calibration ensures high measurement accuracy and the selection of the correct wavelengths. The system can be calibrated to the following parameters: Ammonium, Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), Colour, Dissolved organic carbon (DOC), Total phosphorus (TP), Total nitrogen (TN), Total organic carbon (TOC), Total suspended solids (TSS), Nitrate, Nitrite, Orthophosphate, SAC, Turbidity, UVT
